Femoral Nerve Block

   The important landmarks for this block include the inguinal crease and femoral artery (FA).

  • image   An anatomic study has shown the femoral nerve (FN) to be widest and most superficial at the level of the inguinal crease where it can be found immediately lateral to the artery 71% of the time.

      A. Surface anatomic landmarks relevant to the FN block. IC, inguinal crease; A, femoral artery. An “X” is placed lateral to the FA to identify the site for needle insertion (left inguinal region shown). B.

      Approach and Technique



      1. image   With a high frequency linear transducer positioned at the level of the inguinal crease and oriented parallel to the inguinal ligament, the FA is identified.
